The Daniel K. Inouye Solar Telescope (DKIST) is under construction on the summit of Haleakalā on Maui, Hawaii. Since DKIST will be observing the Sun’s corona, the sky above the telescope needs to be as free of dust, aerosols and pollutants. The isolated islands of Hawaii provide optimal conditions for clear, “coronal skies”.

Have you ever been worried about the impact of an asteroid wiping out human life? Well, I have some disturbing news for you: there is another possibility involving the explosion of a massive star that gives rise to a gamma-ray burst (called by astronomers simply a GRB), when the star ends its life producing a black hole.

The Armagh Observatory has been a staple feature along the Armagh skyline since its creation in 1790. Astronomical research has been undertaken within the organisation since the 1790s and to this day it has seen several different Directors and numerous astronomers walk through its historical doors.

September 2018 will see over 50 astronomers from around the world gather at the Armagh Observatory and Planetarium to discuss the latest news about hydrogen-deficient stars. These stars have lost nearly all the hydrogen from which they were made, to leave only nuclear ash. Astronomers want to learn how these rare and short-lived remnants formed, and what drives their spectacular changes in brightness.

Armagh Observatory, 3rd August 2018: Armagh Observatory reports that July 2018 was much warmer and sunnier than average, with only slightly less than average total rainfall. The mean temperature was 17.0 degrees Celsius (62.6 Fahrenheit), approximately 2.2 C warmer than the long-term (1796–2010) average July temperature at Armagh and 1.2 C warmer than the most recent (1981–2010) 30- year average. This was the warmest July at Armagh for five years. The warmest day (highest maximum air temperature) was 27.1 C, which occurred on the 4th, followed by 26.7 C on the 22nd. Both these maxima wereslightly more than 80 degrees Fahrenheit. The coldest day (lowest maximum air temperature) was 14.4 C on the 11th. The coolest night (lowest minimum air
temperature) was 7.6 C on the 10th, and the warmest night (highest minimum air temperature) was 16.6 C on the 27th followed closely by 16.5 C on the 23rd. The minimum grass temperature was 0.3 C on the 10th, so there were no ground or air frosts.

July 20 1969 saw, arguably, the most famous event in all of human history when Neil Armstrong stepped onto the surface of the Moon and left his footprints there - a mark still indelibly framed in the lunar dust today, some 49 years later. It may seem almost as incredible that it is indeed nearly half a century ago that this epochal event occurred, one that united all of humanity for a short while, as we stared at that yellow orb in our night skies to know that one of our species was walking on it surface.

This article has been inspired by the many questions we get asked here at the Armagh Observatory and Planetarium. We love being asked questions but we thought it would be funny to have a look at the questions you really should never ask an Astronomer. We hope this gives you a bit of a laugh!

This July will be a very astronomically eventful month – full of eclipses, bright planets, meteor showers and bright satellite passes. If the weather permits, we will have the opportunity to witness a lot of interesting events in the night sky.

Welcome to Astronotes

Hello, I’m Heather, welcoming you to Astronotes, the Armagh Observatory and Planetarium’s official blog. Here you will find the latest news and views from all those who work in our organisation, from the fascinating worlds of astronomy and space exploration. We hope you will come here to learn what is hot and exciting, profound or even weird from worlds beyond ours .
So that's the introduction out of the way, now on with the Universe!
